"Hello, we are Those Indecisive People Who Continually Change Their Minds While in the Process of Ordering."

I'm the lady who comes in and stands at the counter and looks over the menu for a good ten to fifteen minutes, pondering what she wants to get. After surveying the choices, I start a strenuous conversation which goes something like this:

CUSTOMER: Hmmmm...I think I want one of those Iced Nirvanas...it sounds good...
BARISTA: OK, will that be all for you?
CUSTOMER: No, I think that's goo- what a minute, do you sell smoothies here?
BARISTA: Yes ma'am, we do.
CUSTOMER: What kind do you have?
(The barista shows the lady the list of smoothies. A few people enter the coffee shop and stand in line behind her. The lady stares at the smoothie list.)
CUSTOMER: I'd like a...is there sugar in the smoothies?
BARISTA: There's real fruit sugars, yes, but nothing add-
CUSTOMER: Oh that won't do. (Barista looks confused) Hmmmm....I don't knoooooooooooooooow...(mumbles) What else do you have that's not coffee?
BARISTA: Well, besides the smoothies, we have Italian sodas and-
CUSTOMER: Oooo, what's that?
BARISTA: It's flavors of your choice in carbonated soda with cream.
CUSTOMER: (pauses) That. I'll have that. What are my choices?
(The barista shows the customer the list of flavors right in front of her, and makes apologetic eye contact with the people in line behind her.)
CUSTOMER: Ummmmmmm...welllllllllllllllllllllll...raspberry sounds good. I'll have that.
BARISTA: (ringing up the order) OK, that'll be two dollars and-
CUSTOMER: Oh wait. (pause) Uhhhhhhhh...can you put flavors in tea instead?
BARISTA: (defeated) Yes. Would you like a raspberry tea instead?
CUSTOMER: Oh, I don't know...(sighs) I'm sorry that I'm taking so long...
BARISTA: If you need some time, I can just serve the people behind-
CUSTOMER: Oh no, I'll have the tea.
BARISTA: OK. Raspberry tea. (voids the old order, rings up the new one) That'll be...
CUSTOMER: Wait. (barista and other customers muffle groans) Raspberry orrrrrr peach...maybe peach would be...(mumbles) You know, I don't think I'm really in the mood for tea.
BARISTA: (exasperated, voiding the tea order, attempting to stay polite) OK, well I need your order, there's people in line.
CUSTOMER: Welllllllllllllll...OK, never mind. I'll just have a Diet Coke.
BARISTA: Is Diet Dr Pepper OK?
CUSTOMER: You don't have Coke? (barista shakes his head) Hmmmmm....welllllllllllllllllllllll...yeah, OK, I guess I can do a Dr Pepper.
BARISTA: (relieved) Alright then, that'll be $1.19.
(The customer pulls out her checkbook. The people in line move up, ready to place their orders. While rummaging for a pen, she notices the pastries.)
CUSTOMER: Oh wait, what is that cake right there?...
(etc etc etc)

It's very nice to meet you.
